Abstract: A headlamp assembly for a motor vehicle having a light source, a chamber that receives the light source and a cooling channel for removing heat from the chamber. A conductive wall and an insulating wall cooperate to define the chamber and the channel. The conductive wall has a substantially higher thermal conductivity than the insulating wall to promote the heat exchange between the chamber and the cooling channel and to reduce heat exchange between the cooling channel and the relatively hot engine compartment.

Abstract: A near field lens for an automotive light assembly which has a reduced thickness. Generally, the near field lens includes a main body of light transmitting material. A pocket is formed in the main body for receiving light from a light source. The pocket is defined by an inner radially facing surface and an inner axially facing surface. The inner radially facing surface is structured to reduce the thickness of the lens.

Abstract: A near field lens is for an automotive light assembly, generally comprising a central body positioned between opposing side bodies. The central body extends in a vertical direction, while the side bodies are positioned on horizontal sides of the central body. The opposing side bodies are structured to collimate the light both horizontally and vertically, while the central light body is structured to collimate the light vertically but not substantially collimate the light horizontally.

Abstract: An LED headlamp array having discrete LED light source modules, where each light source module has an LED light source, optics dedicated to each LED light source, and a faceted reflector.

Abstract: A light assembly and reflector are provided for redirecting light from a light source in a motor vehicle. The reflector generally includes a first parabolic trough, a second parabolic trough, and third trough. The first and second parabolic troughs define first and second trough axes. The third trough has a third trough axis. The first and second parabolic troughs are positioned on opposing sides of the third trough, and the first and second trough axes are angled relative to the third trough axis. In this manner, the reflector collects and reflects a sufficient amount of light while providing control over the beam pattern spread, particularly in the horizontal direction, whereby a single LED may be employed such that constraints imposed by heat dissipation are significantly reduced.

Abstract: A light assembly is provided having a lens assembly that splits the function of a near field lens into two components, thereby permitting a manufacturable lens that achieves the desired beam size and intensity. At the same time, increased flexibility and control over the beam spread characteristics is achieved. The first component is an inner lens, while the second component may be a reflector or a second lens.

Abstract: A LED bulb and light module utilizes a LED light source and directs light therefrom in a manner which improves efficiency and illumination. Ideally, the LED bulb is structured to create a virtual image whereby the efficiency of light directed out of the module is greatly improved, even with a single LED light source. The LED bulb generally includes a light pipe receiving light from the LED light source and guides the light downstream to a downstream portion which redirects the light radially outwardly.

Abstract: A variable multi-source lighting device is provided on both sides of the front part of a motor vehicle to illuminate both sides and/or only one side of the vehicle when driving in a curve. Activation may be determined by the steering wheel or a GPS signal. In use, the device forms a composite light beam composed of partial light beams from individual light sources. Some of the partial light beams are obliquely oriented relative to the vehicle's longitudinal axis and at least one partial light beam is generally parallel to the longitudinal axis. Depending on the vehicle's speed and/or the position of the steering wheel, the sources may be activated individually, in groups, progressively, discretely or continuously so as to increase or decrease the lateral dispersion of light.

Abstract: A lamp assembly including a number of light sources each utilized in conjunction with an optical element. The optical elements include a body of light transmitting material which further includes a top surface, a bottom surface, a front surface and a plurality of facets. The facets receive light through the front surface and reflect light through the top surface. The assembly further includes a manifold defined by the optical elements. When viewed in a direction toward the top surface, a majority of the optical elements have a common shape, preferably a pie wedge shape.

Abstract: An illumination system for delivering light includes a light source, a reflector including a reflective surface adapted to reflect visible light from the light source and to allow heat energy to pass through the reflector, and a housing. The housing includes a base defining a first cavity and a heat dissipation portion extending from said base and defining a second cavity with an opening extending therebetween. The housing is adapted to support the light source and provides a thermal barrier between the housing and the light source. The heat dissipation portion is adapted to transfer heat energy from the reflector to a surrounding environment. A ballast is mounted to the housing to supply power to the light source and a cap is mounted to the heat dissipation portion and is adapted to interconnect the heat dissipation portion to an optical light distribution system.

Abstract: Headlamp system for an automotive vehicle has an individual lamp for illuminating a high intensity zone and a spread zone of an image surface. The system includes a first light source having a substantially elliptical reflector for directing light to a spread light zone on an image surface and a second light source having a filament mounted in an axial direction to the length. A second reflector has a generally elliptical shape, a first focus, a second focus and a magnification. The second reflector directs light to a high intensity zone on the image surface. A light shield having a generally planar surface is mounted substantially normal to the longitudinal axis substantially at the second focus. An aspheric lens having an aperture having a width is located between the shield and image surface. The maximum magnification of the filament at the aspheric lens is substantially the width of the aperture.

Abstract: A central lighting system for providing light to locations remote from the light source includes first and second ellipsoidally shaped reflector members joined so as to substantially surround the light source. The reflector members collect the light output and focus it onto an input face of either a light guide or a non-imaging optical coupling member. If the optical coupling member is utilized, an angle to area conversion occurs so as to allow light introduced at high angles to an input face of the optical coupler to exit the optical coupler at a smaller angle. The reflector members can also be configured so that respective second optical focal points can reside at the apex of the opposing reflector member thereby allowing for a coupling efficiency of approximately 70% or greater.

The length forms a predetermined angle with respect to the horizontal axis to generate light within predetermined a cutoff. A converging lens receiving light from the light source has an optical axis. The lens has a spherical inner surface with a center and an elliptical outer surface having a first and second focal point. The light source is positioned substantially on the optical axis so that the light source is substantially at the center of the spherical inner surface and the first focal point of the elliptical outer surface is substantially coincident with the center of the spherical inner surface.
